I've been wanting to get a second WTF for a while now. I've had my first for about a year. He's in a large tank, 36x17x12 or so, and I was wondering the proper way to introduce another frog. I have read that you should probably keep them separated for about 30 days to make sure the new frog is healthy. I have a smaller hexagonal shaped tank that easily fits inside my current tank. I was wondering if I'd be ok to house the new frog in this tank, inside the larger tank. I don't know if frogs can carry diseases that could become airborne, which is the only way I see a scenario like this affecting my current WTF. I feel that this housing situation would allow for similar temperature, humidity and light as my current tank. Any other way of housing the new frog would require buying a new light housing and a couple other materials. Thoughts and advice would be much appreciated. This is my first post on here although I've read posts on this site many times before. It's been incredibly helpful.
